Project 1: Alarm System

Everyone has things they want to keep secure. Microchips provide a powerful new way of protecting valuables. In this project students will build a simple alarm system that will turn on a buzzer and LED when the alarm is triggered by a pushbutton.

Project 2: Traffic Lights

Not only do people tell microchips what to do, microchips can also tell people what to do. Therefore it is important that they are sending the correct message. In this project students will learn the importance of the instruction sequence and timing functions while building their own traffic light from LEDs.

Project 3: Washing Machine

Microchips have the ability to take over many tasks that once needed to be done by hand. However, these tasks often require a set of instructions to be carried out in a specific order. Students will learn more about giving instructions to microchips while they program their own washing machine.

Project 4: Smart Street Light

Electric lighting has transformed the way people live. However, to produce electricity it is damaging to our environment, therefore it is important not to waste it. In this project, students will make a street light that only turns on when required.

Project 5: Fridge Alarm

The refrigerator is a very useful device that stops our food from going off and keeps it safe from pests. However, they clearly won't work if the door is left open. Students will be making their own fridge alarm to help keep food fresh and save electricity.

Project 6: Temperature Controller

While no one likes being too hot or too cold, there are certain situations where keeping the temperature just right can mean the difference between life and death. Students will use the temperature controller in this project to monitor and adjust the temperature just like in an incubator.

Project 7: Musical Buzzer

While it is pleasant to listen to, music is actually quite complex, and can be difficult to teach to microchips. Students will use this project to make their microchips sing while learning about sound waves.

Project 8: Smart Light Dimmer

Lights that are just on or off are so old-fashioned. In this project students will make a dimmer light that can be adjusted to suit the user's needs in addition to adjusting itself to keep a constant light level in the room while the amount of natural light changes throughout the day.

Project 9: Cool Fan Hat

You'd be the life of the party wearing this funky hat! Students will learn more about sequencing as they make their own flashy hat with a fan to keep cool while flashing LEDs make you look cool

Project Name
Project 1: Windscreen Wiper Controller

Windscreen wipers have several speed settings depending on how heavy the rain is. In this project we will make a wiper that not only has different speeds but can adjust automatically using a sensor.

Project 2: Radiator Fluids Low Indicator

Petrol isn't the only fluid our cars require, and if they run out of water or oil it can seriously damage the car. In this project we will make a water level detector to sound an alarm before it runs out.

Project 3: Trip Computer

Many modern cars monitor your fuel usage and can predict how far you can drive before you run out. In this project we will make a trip computer to monitor the remaining fuel and calculate the range.

Project 4: Electric Car Regenerative Battery

Some cars run on electricity instead of petrol, and can even recharge their batteries when braking. In this project we will make a power monitor that shows the battery draining when we drive, but can recharge the batteries when we brake.

Project 5: Intercooler Spray Controller

Turbo chargers increase your engine's power, but can get very hot. Build a controller that will predict when this will happen and stop it from overheating.

Project 6: RPM Tachometer

Rpm stands for revolutions per minute. A car engine turns about 800 to 5000 rpm Detect the rpm of an electric motor and display it on the LCD.

Project 7: Transmission Gears

When you change gears the ratio of turns changes from the engine to your wheels. Use your LCD to watch how the ratio changes as you move up and down gears.

Project 8: Emissions Control

Servo motors are small motors with their own gears and microchip. Use a servo to control the oxygen going to the engine to avoid too much pollution.

Project 9: Networking in Cars

New cars contain about 200 microchips that need to communicate in a network. Build a network by connecting to other student's controllers and see if you can control them.

Project 10: ABS System

Microchips can sense how fast your car is braking and if it is about to skid on the road. Make it stop quicker using the magnets in your motor.

STEMSEL Environmental Projects

Note: Project 3 requires two wires and a 1K resistor, not present in the STEMSEL kit. Projects 4 and 9 require an additional Servo Motor (STANDARD 4.5V SERVO MOTOR). Project 10 requires an additional LCD display, which is sold as part of Circuit Pack 2.

Project Name
Project 1: Air Pollution Sensor and Indicator

Air pollution may cause diseases, allergies or death in humans; it may also cause harm to other living organisms such as animals and plants. In this project, the students will program for the microchip to measure the air quality and indicate the current pollution level.

Project 2: Street Light with Car Detection Sensor

There are approximately 2.28 million street lighting lamps in serve in Australia. While in the interest of safety, it is important to keep the lights on, they collectively consume large amounts of electricity, nightly. Lights are entirely wasted, without cars and people to see them. In this project, students will implement an energy-efficient street lighting project.

Project 3: Water Quality Indicator

Water is essential to life. However, every year, tonnes of untreated waste is pumped into rivers, oceans and other waterways. Water pollution is one of the most serious ecological threats. In this project, students will build a portable water quality indicator to test the surrounding water sources.

Project 4: Greenhouse Gas Controller

Greenhouses use glass walls and ceilings to provide sunlight to its plants. After prolonged exposure, a greenhouse can become very hot, hence the ‘greenhouse effect’. To avoid plants from withering, greenhouses require maintenance, and a maintainer will open and close windows at appropriate hours. In this project, students will program a controller to open and close a window automatically, based on the current air temperature in the greenhouse.

Project 5: Rubbish Bin with Flashy Thank You

If you have finished your bottle of water or had some rubbish, and you would you do? Through them somewhere on the ground, the side of the road or deposit into a bin. If you put rubbish in the bin, you are contributing into keeping your environment clean and your action will be rewarded. In this project, students will make a happy flashy rubbish bin to encourage when someone throughs rubbish in the bin.

Project 6: Bird and Pest Scarer with Movement Sensor

Birds are a delight to watch and to listen. But most of the farmers do not like them, as they contribute to crop loss every year. However, we cannot kill these pesky birds, which may lead to the huge negative environmental effects. In this project, students will build a system that would keep the birds away from the field by emitting a scary noise.

Project 7: Human Counter

A single light left on overnight over a year accounts for as much greenhouse gas as a car drive from Cambridge to Paris. If you ensure that 10 lights are switched off every night, each year the CO2 emission can be reduced as cutting out 25 flights from London to Paris. There are very important to turn off lights and other electric applicants when they are not in use to reduce the energy waste and carbon footprint. In this project, students will build a human counter system to control the room lighting based on the number of human go in or out this room.

Project 8: Sun UV Indicator

Sunlight is the most important source of the Earth's ecosystem. However, long-term/high-intensity ultra-violet solar exposure can damage human skin. In addition to inconvenient 'sunburn', UV light can be lethal in the form of skin-cancer causation. The device students will develop shall consider both light intensity and time to evaluate danger from UV rays and indicate so.

Project 9: Solar Tracker

Solar power is becoming popular as the main renewable source in the future. However, solar panels only generate maximum power for short time of the day when they are directly facing the Sun. A tilting panel generally produces additional of 30% to 40% than a conventional fixed one. In this project, students will design a solar tracker to track the Sun's path through the sky then aim the PV to the Sun.

Project 10: Solar Battery

Solar energy is becoming more popular. In conjunction with the solar power cell array, batteries can be used to provide power even at night. It is necessary to meet user current demands irrespective of the battery's power status, and hence power from the cells and grid must be redirected between the user and the battery as necessary. If the battery is flat, and solar power is insufficient, this system is also able to calculate the power usage and electricity bill from the utility power supplier.
